The nationwide house energy rating scheme is a way of finding out how much energy a house uses. Just like you have to eat food to get energy to play, houses need energy to work too!
The rating scheme looks at things like how the house is built, how it's insulated, and what kind of appliances are used inside. It then gives the house a score from zero to ten stars.
If a house has a high score, it means it's really good at using energy efficiently, which is like eating healthy food that gives you lots of energy for longer. But if a house has a low score, it means it's not very good at using energy, which is like eating junk food that only gives you energy for a short time.
Knowing a house's energy rating can help people choose a more energy-efficient home, which can save money on electricity bills and help take care of our planet by using less energy.
